这两个英语问题怎么解释？
He thought that web pages which had the most links to them from other web pages must be the most popular.这句话为什么是宾语从句？还有，Page had an idea that this could be achievef by examining the relationships between web pages.这句话为什么是同位语从句，而不是定语从句。
He thought that web pages which had the most links to them from other web pages must be the most popular.
这句话的主句是 He thought， that web pages 置于动词 thought 之后充当宾语成分，所以是宾语从句；而 which had the most links to them from other web pages 则是定语从句，修饰中心词 web pages（网页）。
Page had an idea that this could be achieved by examining the relationships between web pages.
这句话的主语是 Page，had 是动词谓语，idea 是宾语，this could be achieved by examining the relationships between web pages 是宾语 idea 真正的内容，它们是同位的关系，都是充当句子的宾语，因为 this could be achieved by examining the relationships between web pages 是以句子的形式出现的，所以叫做同位语从句。
以THat引导的句子叫从句。从句是相对于主句而言，He thought这是主句。that引导的从句做了主句中谓语动词thought的宾语（主谓宾结构），句子做宾语，这样的句子叫宾语从句。同理，句子做主语，叫主语从句。
同位语就是表达意思相同的词语。如雷锋，一个伟大的战士。二者意思相同，可删除一个。例句that从句是对the idea内容的解释，that在句中无实义，只是引导词，不可省略。定语从句是句子做定语，起修饰作用。引导词that，which，who，有实际意义，在从句中担任主语或宾语，做宾语时引导词一般可省略。区别二者最简单的是按主谓宾结构看他们在从句中是否担任成分，是否可省略，也可以翻译出来按汉语语法区分。This is a good idea that I think about .这是一个定语从句，that做了从句中think about的宾语
